oops

I was at work an extra half hour yesterday trying to correct a closing mistake that I made. It was still unresolved when I left because I needed the store manager to sign some paperwork. Otherwise I covered it okay. I added $0.20 instead of $20. I do not like the calc that we use. People keep resetting the number of decimals making it difficult for me to know how to type stuff in. I thought I figured it out but I was obviously wrong. Stupid mistake too. It could have been avoided by slowing down and rechecking my numbers. I feel really small right now.
